### Question

Further modify the C++ program that you already have modified in Programming Project 2. Change the multiplication sign * in your C++ program to a division sign /. Recompile the changed program. Run the program. Enter a zero input for “number of peas in a pod.” Notice the run time error message due to division by zero.

﻿Modified program code:

``````
#include<iostream>
using namespace std;

//main function
int main( )
{
//Variable declaration
int number_of_pods, peas_per_pod, total_peas;
//Prompt the message, Hello
cout << "Hello\n";

//Prompt the user to enter input
cout << "Press return after entering a number.";
cout << "Enter the number of pods:";
cin >> number_of_pods;
cout << "Enter the number of peas in a pod:";
cin >> peas_per_pod;
//Calculation part by using division symbole
total_peas = number_of_pods / peas_per_pod; //This line
//Display output
cout << "If you have ";
cout << number_of_pods;
cout << " pea pods ";
cout << "and ";
cout << peas_per_pod;
cout << " peas in each pod, then ";
cout << "you have ";
cout << total_peas;
cout << " peas in all the pods. ";

//Prompt the message, Good-bye
cout << "Good-bye\n";

return 0;
}
``````

Output:

``````Hello
Press return after entering a number.Enter the number of pods:200

Enter the number of peas in a pod:10
If you have 200 pea pods and 10 peas in each pod, then you have 20 peas in all t
he pods. Good-bye``````
